Any ideas on why the addItem call in the example code below is very slow
when rebuilding the content of a JComboBox?

The vector typically contains around 50 Strings. On the application this
code sample comes from, there are several similar combo boxes on a
tabbed form that result in the form being very slow to rebuild when new
data is loaded.

    Vector v;
    .......
    String strExample;
    combo.removeAllItems();

    e = v.elements();
    while(e.hasMoreElements()) {
      strExample = e.nextElement().toString();
      combo.addItem(strCompItem);
   }
